Do you mean that the browser doesn't refresh the image properly due to being cached?

If so, can you just append a random number to the filename in the script? <img src=Image.PNG?randomnumberxxx /> so the file name changes as far as the browser is concerned but not with anything else. And then set a meta tag refresh on the html page to refresh at a set interval?

Thank you everyone. Sorry for the delay, I was taken away from this project for a while and now I'm looking into it again.

My comments are in bold.

Are you looking to have an image that changes on the page while the page is being viewed?

Alene

I would like to have the image change. I would like the page to be stable and if possible not flicker.

Is the flicker too disturbing?

Optimally I would like to eliminate flicker. I am open to creative options in regards to that, such as fade from one version of the image to a new one, or fade to black and then to the new image, etc.

Xibo (free) and BrightSign (paid) are two we use here.....

Thank you for pointing me in this direction. I did look into this system but for our needs it is a little outside the scope.

HTML

<!DOCTYPE html><html>

Would that work?

Keep in mind, it requires jQuery, I used 1.9.1 in this example.

I'm not sure if it is me or what but the refresh was not working with this code.

I had read about that issue and that solution which is very interesting. However I was actually just looking for a method to have the webpage refresh at a set interval with minimum screen flicker and minimum code. Meaning no additional utilities flash/java etc.
